What is the definition of project and program?

A project is a work effort made over a finite period of time with a start and a finish to create a unique product or service or result. Because a project has a start and a finish, it is also called a temporary effort or endeavor. In other Words, a project is a temporary endeavor taken to create a unique product, service or result. So, a project has two defining characteristics: It is temporary, and it creates a unique result.

A program may be a part of a higher-level program; it certainly contains some interrelated projects, and it may contain some non-project work as well. Program management focuses on optimally managing the interdependencies among the various projects in the program. The person who manages a program is called the Program Manager.
